2012 IT熱門人才需求類型盤點

Computerworld在對多位IT高管進行調查之后，得出了2012 最需要IT技能，不過由于調查范圍不夠大，可能會出現偏差，僅供參考。

1）編程及應用開發：需求從2010年的44%上升到2012年的61%。
2）項目管理：不僅僅管理人才監管項目，還需要洞察用戶需求并轉述給其他IT員工，包括需求日益增加的商業分析師。
3）服務臺支持/技術支持：隨著移動操作系統的發展，需求隨之增加
4）網絡設計：這類需求部分歸結于虛擬化及云計算的發展，相關人員最好具有虛擬系統及思杰系統經驗的人。
5）商務智能（Business Intelligence）：這類需求大部分歸因于企業日益將重心從節省成本轉向技術投資。
6）數據中心：虛擬化及云技術也排在其后
7） Web 2.0：圍繞社交媒體的技術需求將會增加，Net，AJAX及PHP作關鍵后端技術，HTML，XML，CSS，Flash及Javascript作前端支持。
8）安全：2010年需求為32%，現在有所下降，但由于日趨嚴重的安全問題，許多人又將此提到一個新的高度
9 ）電信：對IP電話技術人員的需求也相當大，尤其是對Cisco IPCC電話中心系統熟悉的人。

Conversion of Oracle TO_CHAR(datetime) with format string to MySQL

The Oracle TO_CHAR(datetime, fmt) function converts datetime values to a string in the format specified by the fmt option.

MySQL has the DATE_FORMAT function that allows datetime values converting to a string in the specified format.

SQLWays converts the Oracle TO_CHAR function to the MySQL DATE_FORMAT function and converts elements of format string from Oracle to corresponding specifier in MySQL as specified in the following table.

近日在項目中寫了個OPhone 調用Webservice的工具類，主要是使用了KSoap2來實現的，代碼如下:

package com.ictehi.ophone.util;
2

import java.io.IOException;
4

import java.util.Iterator;
5

import java.util.Map;
6

import org.ksoap2.SoapEnvelope;
8

11

import org.ksoap2.transport.AndroidHttpTransport;
12

import org.ksoap2.transport.HttpTransportSE;
13

14

29

*/
30

public static SoapObject callWS(String nameSpace, String methodName,
31

Map params, String wsdl) {
32

final String SOAP_ACTION=nameSpace+methodName;
34

SoapObject request = new SoapObject(nameSpace, methodName);
35

SoapObject soapResult=null;
36

if(params !=null && !params.isEmpty()){
38

for(Iterator it=params.entrySet().iterator();it.hasNext();){//遍歷MAP
39

Map.Entry<String, Object> e=(Map.Entry<String, Object>) it.next();
40

request.addProperty(e.getKey().toString(),e.getValue());
41

}
42

}
43

/**

48

// SoapSerializationEnvelope envelope=new SoapSerializationEnvelope(SoapEnvelope.VER10);//SOAP 1.0
49

SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);// SOAP 1.1

} catch (IOException e) {
61

Log.e("IOException:", e.getMessage());
62

} catch (XmlPullParserException e1) {
63

Log.e("XmlPullParserException", e1.getMessage());
64

}
65

try {
66

soapResult=(SoapObject)envelope.getResponse();
67

} catch (SoapFault e) {
68

Log.e("SoapFault",e.getMessage());

調用這個工具類的方法如下：

HashMap<String, Object> params = new HashMap<String, Object>();
2

params.put("theCityName", peoples[position]);
3

String wsdl = "webservice的wsdl地址";
4

String nameSpace = "wsdl中的namespace";
5

String methodName = "方法名";//
6

// SoapObject result = WSUtils.callWS(nameSpace, methodName,
7

// wsdl,peoples[position]);
8

SoapObject result = WSUtils.callWS(nameSpace, methodName, params, wsdl);
9
